The power of nostalgia is fuelling something of a Brummie social media phenomenon with tens of thousands every day enjoying pictures of the city from yesteryear.

Brumpic started as a Twitter page last year and has gone on to share thousands of images of Birmingham from days gone by to a growing audience.

In that short time, it has also seen the nostalgia website showcase its archive at the Birmingham History Gallery at Birmingham Museum and Art Gallery and is the subject of a "Best of Brumpic" free digital supplement on the Birmingham Post's app.

David Oram and Melanie J Reid are the duo behind Brumpic and, writing in the Post this week, they said: "Brumpic began life as a Twitter account in October 2013 purely to raise our own awareness of the city.

"We started off tweeting our own images but soon unearthed an absolute mountain of historical images and so began Brumpic.

"The success of the account in such a short period of time has amazed us, it was never our intention to amass a large number of followers or even spark the interest that it has, it's just gone from strength to strength."

Brumpic sources images from across the internet, including Britain From Above, The Library of Birmingham, Birmingham Museum and Art Gallery, The Cadbury Research Library and individual collections from people such as Geoff Dowling, John Ball, DJ Norton and Phyllis Nicklin.

David and Melanie added: "The huge changes that Birmingham has constantly endured over the last 60 years, some for better, some for worse, evoke passionate and nostalgic memories for many of us.

"The account has taught us that each generation has fond and distinct memories of the city, whether it be the completion of the latest Bull Ring centre in 2003, hanging around 'The Ramp', mooching around Oasis in the 1980s, the building of the Central Library and Paradise Circus in the 1970s or travelling on a tram along Steelhouse Lane in the 1950s.

"The response from the public is occasionally anger, often sadness, mostly fond memories, but always bewilderment as to why Birmingham allowed the destruction of so many fine buildings - the demolition of the Victorian Library, the Georgian houses that were taken down to make way for Rackhams and the building that evokes more response than anything else, Snow Hill Station."

Brumpic is not merely a "Birmingham thing", the pair are keen to point out.

The Twitter account @brumpic has followers from Russia, Japan, Vietnam, Australia, Argentina, over 100 from Scandinavia and more than 500 in the US.

But what of the future? The pair say there is no shortage of images from the past to share and they hope to keep growing.

They said: "The aim of the site is for it to become a great big resource of Birmingham past, present and future. All of the articles on there are from contributors.

"We want the people of Birmingham to come forward and contribute and add to the long list of people that have already got involved.

"Birmingham is much maligned, but rarely bettered. The community spirit, magnificent diversity and our endearing sense of humour make us Brummies what we are and what we will always be."

The gallery above features a selection of images from Brumpic's vast archive. The Post has teamed up with the site to create a free digital supplement which will be available via our app for iPad/iPhone from December 11. Download the app here.
